为了进行水利改良与利用沙地,在辽宁省彰武县阿尔乡建立了试验示范区。试验表明,推平沙丘,可以改善沙地水分状况,提高土壤含水率0.9%~1.3%,沙地利用面积扩大25%~30%；利用地下水,打机井,每3.3 hm2分布一眼,出水量每小时7 t,灌溉农田、药圃、苗圃和速生林；实施微润灌溉,铺设地下管网,保障在旱季土壤湿润,比管道灌水节水2~3倍；实行膜袋植树与覆膜植树法,可节水1倍左右。

In order to improve water conservation and utilization of sand,the experimental demonstration zone in Aer Township of Zhangwu County in Liaoning Province was established.Result shows that:bulldozing dunes can improve the water condition of sand,increase the soil moisture content by 0.9%-1.3%,and expand the utilization area for sand land by 25%-30%;wells were made by using groundwater;a well is distributed every 3.3 hm2;the a-mount of water is seven tons per hour,which used for irrigating farmland,medicine garden,nursery and fast-grow-ing forest.Implementing micro-irrigation and laying underground pipe network can ensure the soil moist during the dry season,and can save water 2-3 times than that with irrigation pipe;using film bags planting and film planting method can save water about one time.
